I think you're wanting an openfiledialog.

also, the issue above is that everytime you click, you're reading and processing the textfile. You will need to clear the items of the comboboc prior to the for each statement

 

 

       Dim ofd As New OpenFileDialog
        ofd.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"
        If ofd.ShowDialog = Windows.Forms.DialogResult.OK Then
            Dim sr As StreamReader = New StreamReader(ofd.filename)
            combobox1.items.clear
            For Each item As String In sr.ReadToEnd().Split(Environment.NewLine)

                  ComboBox1.Items.Add(item)

            Next
         end if
 

Then you will want to double-click on your combobox and in the default event that comes up, set your label = combobox1.text

Hey ,

 Thanks and for the label. I tried putting "Label1.Text = item" or "Label1.Text = ComboBox1.SelectedText" underneath Combobox.items but the label is not changing and showing as I select each line in combobox.
